In order to ensure the stability of the connection between the battery piece and the welding strip, a film piece can be attached outside the battery piece and the welding strip. The film piece is bonded and fixed on the surface of the battery piece to fix the welding strip between the battery piece and the film piece.

[0051] To achieve the above objectives, current methods typically involve adding a membrane processing mechanism and a membrane transport mechanism to the existing battery string bonding equipment. The membrane processing mechanism manufactures the required membranes, and the membrane transport mechanism then transports the membranes to the battery string bonding equipment for use. Existing membrane processing mechanisms generally pull the membrane roll out to a predetermined length and then cut it into multiple membrane sheets using a cutter. The distance between adjacent membrane sheets is very small, which cannot meet the spacing requirements of adjacent membrane sheets in the battery string bonding equipment.
